Can someone please give advice on my Darkrai team. (Ubers)

[Auraice24]

I know the pokemon chosen aren't the strongest, but I want to try things a bit differently.
Usually I send out Illumise and Darkrai first and use sweet scent to lower opponent's evasiveness and then use dark void to put them to sleep. I also just choose Clefariy as some support and Typlosion just for big damage. The Acreus is therer to deal with things like Miraidon and steel types. I see Megerana as a weaker version of Calryex-Shadow-Rider.
Thank you so much if you help me out here :)

Only Arceus-Ground is a viable Pokemon there, and it has a very questionable set. I would recommend checking out some of the sample teams (found here) and the viability rankings (found here) to get a feel for the meta and what the good Pokemon of the tier are.

I'm pretty sure this is Doubles Ubers actually, considering the Clefairy and the lead Illumise + Darkrai, so the relevant resources would be here.
